Application filed August 2li, 1910. Serial No. 578,758.

To all whom it may concern:

Beit known that l, @OTTO MAoxENsEN, a citizen of ythe German Empire,residing at Carl-Zeiss strasse, Jena, in the Grand Duchy ofSaXe-VVeimar, Germany,have invented a new and useful Telescope-Carrier,of which the following is a specification.

The invention consists in an improved carrier for hingedstereo-telescopes.

The carrier as hitherto used is composed of an upperpart or head,forming the carrier proper, and a base part. The base part is adapted tobe mounted on a stand. rllhe top of the carrier head is formed bya-twoparted bearing for the hinge bolt of the stereo-telescope. The headand the base part are joined with each otherr through a hinge, whichallows the head to be inclined to some extent in the vertical sightingplane and thus serves orwertically pointing the telescope.l lhis hingeisequipped with an axial clamping screwj The head extends so far upwardthat even in the stretched (horizontal) position of the hingedstereotelescope the clamping screw is still accessible, because allparts of the telescope lie above the level of the carrier hinge.

According to the present invention the head of the carrier istransformed toextend so much less upward that the center of gravity ofthe hinged stereo-telescope,.when the latter is supported in itsstretched position, lies about 1n the axis of the carrier hinge, aboutwhich the telescope is to be rotated. for being pointed vertically. rlheuse of the hinged stereo-telescope is in-th'is way considerablyfacilitated, because the stretched position is principally employed. Thesaid transformation so much reduces the Weight of the head that thecarrier can henceforth remain joined with the hinged stereo-telescope.In this case the head can be simplified by shaping the bearing for thetelescope hinge bolt as an undivided bearing or sleeve. The clampingscrew of the carrier hingefcan be radially arranged, for instance in thehead, when the latter is provided with the` bearing of the carrierhinge. ln'the'latter case the base part Vof the carrier comprises thejournal of the carrier hinge, and when it consists only of this journaland is adapted to be mounted on an upright stand'v pivot by means of avertical and radial bore, it may be divided along this bore with theefect that'the radial clamping screw, in addi- `the head tionl tohindering the rotation of the head about the carrier hinge, suppressesthe rotatability of the carrier o n the stand pivot.

ln the annexed drawing: Figure l is a section along the verticalsighting plane through a carrier forv hinged stereo-telescopes,constructed according to the invention, the position of the telescopebeing indicated by dotted lines. Fig. 2 is a back View of thisarrangement. Fig. 3 is a hori- Vzontal section on line 3 3 of Fig. l. 2

'llhe bearing 0,0 of the carrier hinge appertains to the head. rlfhetwo-parted journal 251 b2 of this hinge, forming thebase part ofthecarrier, is retained in the bearing a0 by a cover c. As may be seenfrom Fig. 2, the j ournal and the bearing are sufliciently short in thedirection of the axis as to accommodate to the narrow space between thelimbs ZidZ of the telescope when stretched. The telescope` is mounted bymeans of its hinge bolt c in the undivided sleeve al of the head. Aclamping screw f is radially arranged in the bearing a0; For the purposeof receiving the upright pivot of the stand head g, a bore 6 is providedin the base part b1 b2. Along this bore the two parts b1 and b2 of thejournal are joined together in such a manner that the part b2, that isimmediately' 1. A carrier for hinged stereo-telescopes, Y
